The TUC in Yorkshire appealed on Friday for widespread support for 500 health service staff who start a five-day strike on Monday over pay cuts.
Mid-Yorkshire Hospitals NHS Trust wants to impose "down-banding" of pay to its clerical and administrative staff as part of £24 million cuts imposed by the government.
Public-sector union Unison says the cuts will cost workers £1,700 to £2,800 a year.
As reported in the Morning Star this week, the staff start the third in a series of strikes on Monday, when they launch a five-day stoppage culminating in a rally in Wakefield on Friday.
Yorkshire and Humber TUC is appealing to the labour movement across the north to support the staff, who will be mounting pickets at the trust's three hospitals on Monday morning.
